Respuesta :
Cl- implies that it is a chlorine atom with a negative charge (chloride ion), meaning it is an anion
Answer: Anion
Explanation: Anion is a species which is the negative species formed by the gain of the electrons.
The electronic configuration of Chlorine is
Cl = 1s2 2s2 2p6 3s2 3p5
If an electron has been gained, then it will be placed under the 3p orbital. And as it has been added, it will appear as a negative sign.
Cl- = 1s2 2s2 2p6 3s2 3p6
